National air pollution map

Our investigation into air pollution uses results collected by you.   

Have a look at the results so far from across the country, put together using information from our Clean Air Kits.

Tips for exploring the map

Enter your postcode on the map above to skip straight to your street. You can also tick or untick the boxes floating over the map to show more or less detail.

What do the map icons mean?

   Higher air pollution snapshot means the tube was over the level at which the mean annual limit is set (40µg/m3)

  Lower air pollution snapshot means the tube was under the level at which the mean annual limit is set (40µg/m3)

 Local groups monitoring sites are the sites where our local groups have placed air monitoring tubes. 

NB All the results from the diffusion tubes required calibration and adjusting alongside government figures. This is called a bias adjustment. We’ve spoken to experts in monitoring and have adjusted all the results for accuracy using a bias correction factor for the type of diffusion tube used.

Air pollution is a lethal problem.

It's responsible for 40,000 early deaths in the UK each year. 

Using our Clean Air Kits, people have started investigating the air where they live. We've put the results on our UK-wide air pollution map above to show the full scale of the problem.

Every point of this map shows where someone has put up an air monitoring tube. It shows where the tube was placed, and what the result is.

What do the results mean?

The air monitoring tubes on the map measured nitrogen dioxide (NO2).

The European Union has set a legal mean annual limit for NO2 at 40µg/m3 (micrograms per cubic metre).

Weather has a large effect on levels of air pollution, so the results displayed on the map can only represent a snapshot of the air pollution for the place and time they were measured.

They can look very different from the annual mean – and are not directly comparable.

Most areas of the UK are currently failing to meet legal limits set by the EU. And even at low levels, short term and long term exposer to NO2 can have significant negative health effects.

Cancer, heart disease and asthma have all been linked to poor air quality. Children are at particular risk, with air pollution damaging the development of their lungs.

We know there are a number of solutions, the most urgent is getting the most dangerous vehicles off the road.
